[0002] The current laboratory vacuum filtration pump lacks condensing equipment, which makes it impossible to filter steam and other harmful substances from the exhausted air. It lacks silencing facilities, which results in high noise and strong vibration during use, which affects the life of the equipment. Excessive noise affects the laboratory's scientific research environment. It lacks a gas detection device, which may produce many harmful gases in the experimental environment. The lack of a detection device may cause pollution to the experimental environment and harm to the human body. The existing vacuum filtration device (publication number: CN210251415U) has the following problems in use:

[0003] 1. The current laboratory vacuum filter pump lacks condensation equipment and cannot filter steam and other harmful substances from the exhausted air, so a vacuum filter pump that can perform condensation is urgently needed;

[0004] 2. Lack of silencing facilities. The equipment has high noise and strong vibration when in use, which affects the equipment life. Excessive noise affects the scientific research environment of the laboratory. Therefore, a vacuum filtration pump with vibration and noise reduction function is urgently needed;

[0005] 3. Lack of extraction gas detection device. Many harmful gases may be produced in the experimental environment. Lack of detection equipment may cause pollution to the experimental environment and harm to the human body. Therefore, a vacuum filter pump that can detect exhaust gas is urgently needed.
